JET-TY.

Application filed August 28, 1826. Serial 1T0. 180,827.

My invention relates to improvements in jetties.

The object of myinvent-ion is to provide a jetty which will serve as a revetment to protect a river bank and its bed, wh1ch 1s sim le, cheap, easily and economically 1nstal ed, whic is strong, durable, n0t l1able to be broken u or displaced, which will collect and hold riftwood, stones and soil and Which is efficient in its operation.

My invention provides further a novel mat or mattress for revetment use on a bank and in a river.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawings, .which illustrate the preferred embodiment of my invention, l

Fig. 1 is a plan view of my improved etty shown anchored in a stream.

Fig. 2 is a section on the line 2-2 of Fi ig. 3 is an end elevation of some of the connected units of different transverse rows of jetty units which form part of my 1mproved mat.

Fig. 4 is an enlarged EBISPGCUVG view of one of the jettyunit-s w ichI employ in my improved jetty mat.

Fig. 5 is a side view of a portion of one of the jetty units, enlarged.

Fig. 6 is an enlarged perspective view of one of the longitudinal anchoring cables, portions of connected connecting said units.

Similar reference characters designate similar parts in the different views.

My improved jetty mat comprises a ser es of rows of connected jetty collecting units arranged transversely to a river on its bank and on its bed, the rows being anchored to the bank against movement transversely and downwardly with respect to the current of the river. v

Referring particularly to Figs. 4, 5 and 6,

each collecting jetty unit whlch I prefer.

to employ, comprises a longitudinal angle bar 1, to which are fastened two sets of crossed angle bars2. Wires 3 connect the corres onding bars 2 of the two sets of crosse bars. Wires 4, connect the crossed bars of each set with each other, and wires 5 connect the cross bars 2 with the longitu lecting jetty units arranged in rows transdinal bar 1. The ends of the bar 1 has fastened to it eyes 6.

As shown in Figs. 1 and 2, the units corjetty units and links responding to the one just described are disposed in transverse rows, links 7 bein used to connect the adjacent ends of the a jacent units of'each transverse row. Similar links 8v connect the adjacent ends of adjacent cross bars 2 of the different rows, the units being. preferably disposed also in longitudinal rows, Fig. 1.

For anchoring the mat against transverse movement, anchoring cables9, res ectively connected to posts 10 on the river Bank 11, are respectively connected to the adjacent eyes 6 of the different transverse rows, Fig.4.

For anchoring the mat against movement down stream,two longitudinal cables 12 are fastened at their upper ends to posts 13 on the bank 11, and are connected tothe outer eyes respectively of the different transverse rows of units.

Intermediate longitudinal anchoring cables 14 are respectively fastened to osts 15 above the mat and are fastened to t e links 7 of the lowermost transverse row and are slidably mounted respectively in links 7 of the other transverse rows, Figs. 1, 2 and 6.

In the operation of the jetty, the connected jetty units and cables will form a mat or mattress which will collect material washed down by. the river and-will prevent further erosion of the bank and river bed.

Owing to the flexible connections between the units, the mat will conform to the bank and river bed.

I do not limit my invention to the struc ture shown and described, as many modifications,-within the scope of the appended claims, may be made without departing from the spirit of my invention.

What I claim is 1. In a jetty, a jetty matcomprising collecting jetty units arranged in longitudinal and transverse rows, spacing connectors con. necting the units of each transverse row with each other, spacing connectors connectin the units in the longitudinal rows with eac other, spaced anchoring transverse cables respectively connecting with the adjacent, I

units of the transverse rows, and longitudinal anchoring-cables fastened to the lowermost transverse row of units and having longitudinal slidable connection with the other transverse rows of units.

2. In a jetty, a jetty mat comprising colversely to a stream, connectors connecting the units of each row, connectors connectlng the rows with each other, transverse cables respectively connected to the adjacent units of said rows for anchoring the mat from transverse movement in a stream, two lon itudinal anchoring cables connected to tie outer ends respectively of said rows, and intermediate longitudinal cables anchored at their upper ends and at their lower ends being fastened to the lowermost row of units and slidably connected with the other rows.

3. in a jetty. a jetty mat comprising collecting units arranged in transverse rows, links connecting the units of each row with HENRY F. KELLHER.
